I was under the impression that there's no means of getting 18.04 (or 18.10) for the Pi, short of doing an upgrade from the command line. Please elaborate if many of us are mistaken in that understanding...

You can install via the debian/text installer. See AArch64 on Raspberry Pi 2 (rev 1.2), 3B, 3B+ - #37 by stillwinter . On that thread there is also a live installer for xubuntu arm64. And an image for armhf.
